To shim, or not to shim.........

[thejackal]

Morning all

I have a mid 80's Raleigh bike, with a what I measured at 25.4mm diameter seat post.

I have purchased (from Lazarus, on here) a gorgeous Campagnolo 25mm seatpost.

There is, perhaps obviously, a small amount of movement when I insert the new seat post into the seat tube. Can I get a shim of 0.4mm? Or do I just tighten the seat tube until it holds? Or, do I do a Blue Peter stylee type solution and fabricate something myself, possibly out of a used bean tin. Seriously! I'm guessing that the thickness of a bean tin would be aboiut the required thickness...........

Nothing wrong with that, and if you look here...

You can save yourself the Blue Peter bit, although I have done so myself...

You'll be pleased with it when it arrives; I've used one of those USE ones in the past and it's a good product. Slightly beefier collar at the top stops it falling down into the seat tube, which I have done with home-made seatpost shims in the past!

Hi Jackal Sorry to hear the post wasn't the right size, but pleased you have overcome the obstacle Have to confess I'm not familar with a 25.4mm until now. 26mm upwards is all I've encountered to date. My best to you, yours Laz.
